Dinosaur National Park       This national park was created on Oct. 4, 1915, and contains numerous fossil remains of the Jurissac Period, about 149 million
Richard Erwin                     years ago. The dinosaur fossils were discovered in 1909 by Earl Douglass in a sandstone and conglomerate layer known as the
9/21/2013                          Morrison formation. The area was originally a river bed and speculation is that a series of drought and flooding events caused
                                          the many animals to be trapped and later buried in this location. Over the years since that time, the river bed has been uplifted
                                          to its present angle (67 degrees) by the mountain building that created the Uinta Mountains. Although the quarry and the visitor's
                                          center is in the state of Utah, the park, which includes 200,000 acres lies mostly over the border in Colorado.
